I need friends to hang out with after work! (Jakarta)

Hello!
I'm swedish/chilean/catalan , I just came from New York and I'm going to be here for three months working!
As everyone else I work alot during the days and have found it really difficult to know where to go, what to do, and who to talk to after work. I don't know anyone here outside of work and I really long for someone to talk to and just have fun, have a couple of beers, try out some restaurants or, go to museums, trips, go to music-shows.
So if there's a crowd out there already doing all these things please! count me in!
Im up for it !
